Flushing backwards can cause seal leakage and
flush media will enter the product zone.
CAUTION
1. Apply a suitable lubricant to all O-rings and insert them in their
respective grooves.
NOTE
: Place the seal seat O-ring over the seal seat and then
insert the seat into the rotor.
2. Follow the disassembly procedure in reverse order to com-
plete assembly. Torque the rotor nut to approximately 75 ft-lb
(102 N·m).
3. The seal water to the mill must be connected to the gland
connection marked IN (the ports are stamped “IN” and
“OUT”). The inlet of the gland contains the smaller (1/8”) hole.
The outlet contains the larger (1/4” hole). (See Figure 19).
The mill can be adjusted to have a clearance between the rotor and
the stator from a minimum of 0.010” (0.254 mm) to a maximum of
0.240” (6.1 mm), in incre ments of 0.001” (0.025 mm).
The body and the adjusting ring are calibrated as a unit and serialized;
they must not be interchanged with other Waukesha Cherry-Burrell
brand Colloid Mills.
The stator is held firmly against the adjusting ring by “T” handles
(Figure 21).
Adjust the clearance between the rotor and stator by turning the
adjusting ring counter-clockwise (when facing the outlet port) to
increase the clearance, and clockwise to decrease the clearance.
The adjusting ring is engraved with numerals indicating the clearance
in increments of 0.010” (0.254 mm). The indicator pointer indicates
the desired clearance. For setting in between the increments of
0.010” (0.254 mm), the drill point spacing is equal to 0.001” (0.025
mm) clearance. The drill point spacing coincides with the locking
hole spacing. There are 18 locking holes in the ring, spaced 20°
apart (Figure 20).
Rotating the ring by 20° (hole to hole distance) changes the milling
clearance by 0.001” (0.025 mm).
Example: to obtain 0.014” radial clearance, locate the 0.010 punch
mark under the pointer. Turn the ring counterclockwise four additional
drill points (or locking holes), and lock it in place with the knurled lock
screw (Figure 20). Tighten the “T” handles to firmly hold the stator
against the adjusting ring. The clearance will be 0.014” (0.36 mm).
Adjust the lock bolt and tighten the nut (Figure 21).
